Vishay Intertechnology has recently launched two new 1.25M current mode boost converters, specially tailored for white LED drivers. The two models are SiP12510 and SiP12511.
According to the company's product data, both types of LED drivers use an input voltage of 2.5-6V, the output SiP12510 can be 17V, and the SiP12511 is 28V. Internally set power switch and 1.25MHz high frequency snubber to reduce board space to save board space. At the same time, these two drivers support linear and PWM regulation technology, so that the brightness of the LED can be controlled. The driver's most distinctive feature is the integration of many protection functions, including overvoltage protection, and a ramp-up of 0.55A protection, while using three 20mA serial outputs to limit the current gradually rising, in the ?6. Effectively reduces the peak current. When it exceeds 165 °C, overheat protection will cut off the line. Therefore, the product shows its humanity and security.
These two new products are available in a SOT23-6 package. Because the new product achieves 90% high conversion efficiency over the entire industrial temperature range of -40 to +85 °C, and less than 1uA of quiescent current and small form factor, it is ideal for use in space-constrained, battery-powered products. Portable mobile device applications including mobile phones, PDAs and digital cameras.
